The Hubble Space Telescope UV Legacy Survey of galactic globular clusters - II. The seven stellar populations of NGC 7089 (M2)

Milone, A. P.; Marino, A. F.; Piotto, G.; Bedin, L. R.; Anderson, J.; Renzini, A.; King, I. R.; Bellini, A.; Brown, T. M.; Cassisi, S.; D'Antona, Francesca; Jerjen, H.; Nardiello, D.; Salaris, M.; van der Marel, R. P; Vesperini, E.; Yong, D.; Aparicio, A.; Sarajedini, A.; Zoccali, M.


We present high-precision multiband photometry for the globular cluster (GC) M2. We combine the analysis of the photometric data obtained from the Hubble Space Telescope UV Legacy Survey of Galactic GCs GO-13297, with chemical abundances by Yong et al., and compare the photometry with models in order to analyse the multiple stellar sequences we identified in the colour–magnitude diagram. We find three main stellar components, composed of metal-poor, metal-intermediate, and metal-rich stars...[Show more]
